Route Selection Strategy Combined With Spectrum Characteristic in Cognitive Radio Networks

This paper mainly considers the path stability and the interference to primary users. Stochastic processes and probability theory is used to analyze the spectrum stability. Furthermore, the path stability is analyzed. Additionally, a more conservative approach is proposed to measure the interference to primary users in order to protect primary users as much as possible. One could draw the conclusions that MMIM method is more effective than random selection method. This paper represents a first step in designing routing protocols in decentralized cognitive radio network. The authors will extend the proposed solutions to address more practical scenarios, and complete the routing protocols, such as routing discovery as well as repair in future work.
